Hotels with All Inclusive

When you travel with children, studying the menu and doing quick math before every extra order, or paying at the counter each time someone wants a drink, wears you down more than you would expect. Plenty of families say they never quite relax, because every time a child asks for another drink, they find themselves thinking about the bill.

At an all inclusive property, meals, drinks, and on-site activities are built into the room rate, so you can spend the whole stay without watching a running tab. Your child can drink as much as they like and you can grab a snack in the lounge, and the price stays the same. That peace of mind is a big draw for families.

Across Japan, these properties cluster in the resort towns and hot spring towns that families already know. By area, you will find many in Toba, Beppu, Lake Toya, Yatsugatake, Minami Boso, Ishigaki Island, and Atami. By brand, Mercure and Grand Mercure lead with more than 20 properties. Beyond those, the lineup is wide: Club Med in Hokkaido and on Ishigaki Island, Manseikaku at Lake Toya, and hot spring hotels such as Grandia Housen in Awara Onsen.

One thing to watch is that what is actually included varies a great deal from property to property. Some cover alcohol with no limit, some cover only soft drinks and dinner, and some charge separately for paid activities. Even in 2026, each property defines its plan differently, so checking exactly what is covered at the time of booking keeps the day itself from surprising you.

The phrase "all inclusive" makes some travelers picture a beach resort in Europe or the Americas, but the Japanese version has a slightly different shape. It centers on the large communal hot spring baths, buffet dinner and breakfast, and free-flowing drinks in the lounge, so what is included is mostly food and drink. The Western style that folds in marine activities and a kids' club is represented mainly by Club Med, at Ishigaki Kabira and at Tomamu in Hokkaido.

If you are traveling with a baby aged 0 to 2, look for a property with a baby cot in the bath changing room, a nursing room, and baby food on offer. Grand Mercure Nasu Kogen and Grand Mercure Yatsugatake let children who are not yet out of diapers into the bath tubs, and both lend baby cots and hold Welcome Baby certification, a Japanese accreditation for baby-friendly stays. Up in Hokkaido, Hotel Naturwald Furano and Noboribetsu Manseikaku have the same class of facilities.

If you want somewhere elementary schoolers can burn off energy, Hotel Katara in Izu Atagawa Onsen is an easy pick. It has one of the largest kids' playrooms in the region, an all-weather pool, an indoor jungle gym course, and kids' programs. Grand Mercure Awaji Island also offers outdoor and indoor jungle gym courses plus kids' programs, and ANDA RESORT IZUKOGEN includes its on-site activities and 12 hot spring baths in the rate.

If budget is your deciding factor, think in three tiers and the choice gets simple. The 10,000 yen range is anchored by the TAOYA line from Ooedo Onsen Monogatari, with 14 properties nationwide, in places like Atami, Gero, and Akiu, all built around buffets and hot springs. The 20,000 to 30,000 yen range is the nine Grand Mercure properties. Above 50,000 yen you move into the luxury tier: Club Med Ishigaki Kabira, 730 HOTELS. on Ishigaki Island, and Hakkoda Hotel.
